Buy at carrier rates,sell at yours
Compare every seller's rate and stated quality for a destination, price the exact number, and let least-cost routing do the buying. One fee on the carrier rate, capped at $0.001, and no monthly minimum.
Choose your own routes, at the rate the seller sets
Carriers list their routes and set their own prices. You compare them, buy the ones you want, and let least-cost routing send each call on the lowest price, the best stated quality, or the best quality for the money.
Compare every seller
Each destination lists every seller’s rate, caller ID type, billing increment, capacity and stated quality, side by side.
Price the exact number
Type a number and every route is ranked by what it would charge for that number, on the longest matching prefix.
Buy and connect
No setup fee. SIP credentials or IP authorisation are issued with the purchase, so traffic can flow straight away.
Pay per call
Each call is charged from your prepaid balance against its call record, which buyer and seller can both audit.
One small fee on the carrier rate, capped
No monthly fee and no minimum on marketplace traffic. The only charge on top of the seller's rate is a percentage that never passes a tenth of a cent.
Calls you send switch-to-switch over your own SIP trunk. This is how most carriers connect, and it carries the lowest fee.
Calls and SMS sent through the REST API, MCP or the Dialer. Short calls to cheap destinations pay a fraction of the cap.
- What is covered
- These are the only platform fees on ordinary voice and SMS traffic, wherever it terminates.
- How voice is timed
- Each route bills on its own increment, shown on the route: 60/60, 6/6 or 1/1 (the first billed block, then each step, in seconds).
- How you pay
- Prepaid. Top up from $5 by card or crypto, or $100 by bank wire, and traffic draws down from the balance. You can never owe us money.
- Codecs
- G.711 and G.729.
- What sits outside it
- AI voice agents ($0.25 per AI-connected minute), phone numbers (a setup fee plus a flat monthly price) and the Switch, a separate subscription.
Every other charge is itemised on the developer pricing page.

No seller fee. You keep your full rate.
List a route from the rate sheet you already have and every buyer on the marketplace can see it, without learning who you are. Each call credits your full listed rate to your balance; the platform fee is the buyer's. Request a payout by wire or crypto from $50, and our team processes each request by hand.
List a routeRun your own customers on the Switch.
A separate monthly subscription with every module included and unlimited minutes switched, from $500 a month for 500 concurrent calls to $10,000 for 25,000. Call termination is billed separately. Beyond 25,000, talk to sales. Route groups add failover between suppliers, and invoices, payables and netting follow from the same calls. Free trial by application.

Do developers pay a different rate?
No. Developer and Carrier accounts buy on the same marketplace at the same seller rates. The fee depends on how traffic reaches us: 0.5% over your own SIP trunk, 2% through the API or Dialer, both capped at $0.001.
How do I connect my switch?
Buy a route and send SIP to our edge, authenticated by IP (no registration) or by the username and password issued with the purchase. Codecs are G.711 and G.729. The connection details are public.
Can calls fail over to another route?
Failover between suppliers runs in Switch route groups, retried on the SIP codes you choose. On the marketplace you choose the route, or let least-cost routing pick it per call.
What do the quality figures mean?
A listing shows its ASR, ACD and NER measured on real buyer calls once it has carried enough of them, beside the ASR, ACD and PDD its seller states. The Exchange Score is our 1-100 rating calculated from those figures and the route's tier, and a route shows as unrated until it has carried traffic. Raise a failed call as a route issue and the route is re-tested.
How do I pay, and is there a minimum?
Prepaid, with no minimum and no monthly fee. Top up from $5 by card or crypto, or $100 by wire. If the balance runs out, traffic pauses; there is no invoice at month end.
How do sellers get paid?
Each call credits the seller's balance with the full listed rate. Sellers request a payout by wire or crypto from $50, and our team processes each request by hand.
